"My skin graft is a cortosis mesh–a holdover from the days when I advised manufacturers in the field late in the Clone Wars. I can assure you, young lady–every bolt you fire against me will carry directly into your friend."

Cortosis was a material that could be found on the planetsDinzo[1] and Mokivj.[2] Cortosis had a very high energy absorption rate and transmission coefficients, which allowed even the energy of a blaster bolt to be dissipated upon contact. It could also redirect the heat of explosions, as discovered when General Anakin Skywalker attempted to collapse the entrance of a cortosis mine, and the resulting explosion breached through Mokivj's crust. Despite these advantages, cortosis was very fragile, making it normally useless as armor, and had difficulties with prolonged energy attacks, such as those of lightning guns, which would overload the material.[2]

During the Clone Wars, the Grysks, who used cortosis for energy management, told CountDooku of an effective way to use cortosis against the Galactic Republic. By specially weaving cortosis fibers within a protective matrix, it was possible to create armor that was both durable and immune to blaster fire. The cortosis armor also redirected the energy of a lightsaber back into itself, causing the lightsaber to temporarily shut down upon contact. Duke Solha was placed in charge of creating B2 super battle droids equipped with the armor and, under the supervision of Darth Sidious, clone armor that could be used for Order 66. This was discovered by Padmé Amidala, Anakin Skywalker, and Thrawn, who proceeded to destroy the clone armor and sabotage the battle droids so they would overheat minutes after activating.[2]
